> Morality and law are not always aligned
This is a significant philosophical point.
The thing about that Lord Moulton said is that there are a bunch of things that are wrong that are not illegal, and we have to do that because people have to be capable of self-control. Patrick Deneen, in . . . The Failure of Liberalism said that he thinks liberalism is failing because it has come to the view that anything that is not illegal is moral.
Is it immoral for Jensen to cheat on his wife?
What if he "believed fidelity was the wrong move" and that he'd end up divorced eventually anyways?
When is disloyalty and dishonesty immoral?
It’s something you are not equipped to judge. You don’t know much about his private life and the private life of the people around him. Having sex in itself is not the problem, and so far what was demonstrated was that he had sex, at least one with an alleged spy evading trade sanctions, and once with a subordinate. Either are improper and ground for firing; both together are untenable (plus the possibility that there are other skeletons; we don’t know for now).
The relationship with his wife is neither here nor there, unless she wants to make it public. If she feels betrayed, wants a quick buck, or otherwise wants to for any reason, she will sue for divorce and, considering the publicity of the cases, she should get a favourable judgement.
It’s easy to impose our morals on others. But more than half of republicans believe that gay sex is immoral just as strongly as you believe that adultery is.
In this case, though, I think Huang just believed these sanctions were the wrong move, and would end up long-term helping China and hurting the US. Which is fair to believe, but believing a law is counterproductive doesn't give you immunity if you break it.
